Baltali Gate, or the Gate with Axe, takes its name from the double axe relief on the keystone of the arch. This gate was part of the aqueduct which brought water to the ancient city. It is not known whether the gate was also part of the city walls, as long as no remains of them have been found, or was a gate erected by the city in the honor of an emperor. However, because of the eyes engraved on the double axe (the symbol of Zeus Labrandos), it is thought that the gate might have carried a symbolic cult meaning, as the eyes look in the direction of Labranda (see below) so that the god could keep watch on the sacred way and protect the people going to attend the festival held every year in Labranda. The capitals of the piers are decorated with flutes and palmettes, thus reminding of the capitals of Gümüskesen memorial tomb which means that the gate was also erected at the same period, in the 2 century AD.
